Specification of Letters Patent.

Patented July 17, 1917.

Application filed May 9, 1916. Serial No. 96,359.

To all whom t may concern:

Be it known that l, ARTHUR T. Bnrr'roN, a citizen of the United States, and a resident of San Jose, in the county of Santa Clara and State of California, have invented a certain new and useful Improvement in Tilling-Machines, of which the following is a specification.

My invention relates to improvement in a machine for tilling the soil, and the objects of my invention are:

First, to provide a tilling machine that can be operated and drawn by a traction engine.

Second, to provide a tilling machine for tilling the soil, that will till the soil in two layers, placing the lower stratum over the surface stratum, and thereby covering all weeds and other debris under the lower stratum of the soil.

Third, to provide a tilling machine that will leave the surface of the ground well broken up and smooth, thereby avoiding the use of a harrow for smoothing the surface of the ground, as is now in use after plowing.

A Still further object of my invention is generally to improve this class of tilling machines for tilling the soil, so as to increase their utility, durability and efficiency.

Further objects and advantages will appear in the following description, it being understood that various changes in form, proportions and minor details of construction may be resorted to within the scope of the appended claims.

F or a full understanding of the invention and the merits thereof, reference is to be had to the following description'and accompanying drawings, in which, j y

Figure 1 is aside elevation of my trilling machine showing the" general construction thereof, parts broken away.

Fig. 2 is a plan view of my tilling machine showing general arrangements of parts.V v

Corresponding and like-parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

Referring now more particularly to the drawings, 1 is the main frame of my tilling machine to which is attached wheel crank levers 2, by bearings 3, said bearings being held in place on frame 1 by bolts l, connected to said crank levers 2 are fulcrum pins 5, on the lower end of said crank levers 2 wheels 6 are mounted on axle pins 7. Said crank levers 2 are for the purpose of adjusting the depth of surface soil to be tilled, and for elevating the machine above the surface soil when so required, connecting rods are shown at 8 adapted to operate said crank levers 2 and said wheels 6 by the operator from a traction engine, said tilling machine being drawn by draw-bar connection 9 fastened to frame 1 by bolts 9a, a draw bar connection 9" is shown at the rear end of frame 1 fastened to frame 1 by bolts 9. Said tilling machine is operated by power shaft 10 connecting with a traction engine not shown, said power shaft 10 connecting with worm drive 11 by universal joint 12, said worm drive 11 being held in place on frame 1 by bearings 13 and bolts 14, said worm drive meshing with worm gear 15,

said worm gear being positioned on shaft 16,

said shaft 16 being held in place on frame 1 by bearings 17, said bearings being bolted to frame 1 by bolts 18. 0n one end of said shaft 16 is fastened sprocket wheel 19, to

which is connected sprocket chain 20, leading to sprocket wheel 21, said sprocket wheel 21 being fastened to shaft 22, said shaft 22 being held in place on the underside of frame 1 by bearings 23 and bolts 24C. Fastened to said shaft 22 is toothed drum 25, in f which is positioned a plurality of steel teeth 26, adapted to till the surface soil and be replaced from breakage or wear. On the driven end of said shaft 22 is fastened f sprocket wheel 27, connecting with sprocket .wheel 27 is sprocket chain 28 leading to sprocket wheel 29 fastened to the driven end of shaft 30, said shaft 30 being held in place on top of frame 1 by bearings 31, and bolts Fastened to said shaft 30 is toothed drum 33 in which is positioned a plurality of steel teeth 34, meshing with teeth 26 in drum 25, the same being adapted to clean the weeds and grass from said steel teeth 26, said teeth being adapted to be replaced after breakage or wear, said sprocket chain 28 passing over sprocket wheel 35, said sprocket wheel 35 being held in place by bracket 36, and axle pin 37, said bracket 36 being fastened to the under side of frame 1 in any suitable manner. rlhis sprocket wheel 35 is for the purpose of taking up the slack of sprocketr chain 28.

A right and left screw soil conveyer is shown at 38, held in place through frame 1 Y by bearings 39 and bolts 40. Fastened to the louter end of said screw soil conveyershaft 38a, is sprocket wheel41, andsprocket wheel 42, sprocket chain 2S meshing with f sprocket wheel 41. Shaft 43 is shown c'on nected to the under side of frame 1 by bearings' '44,A and held in placezby bolts ,45, fasi tened to said shaft 43 is toothed drum 46 in which is positioned a vplurality 'of steelV Ateeth 47, thesame being adapted to tillthe 'lower -stratunrof the soil'and are 'interchangeable in said drum 4G after breakage 1"we`ar; On the Vdriven end of saidsh'aft 43, is fastened sprocket'-whee'l 48, sprocket chain 28 meshing therewith."
